What problem does it solve? Self-modifying agent systems risk applying their own proposed changes without oversight. This Skill enforces a privilege boundary: producer skills can only stage candidate patches, and only this human-invoked applier can land them, with a fresh cross-model jury verdict obtained at landing time. ## Core Features & Use Cases - Jury-at-landing verification: Runs a fresh cross-model review (via codex MCP) on each staged diff at apply time, ignoring any producer-written verdict that could be forged. - Provenance stamping: Records author, reviewer, verdict ID, and content hash on every landed change via a provenance helper, with cross-family author/reviewer enforcement. - Reversible mutations: Backs up every target file before applying patches and logs each landing to an audit trail. - Use Case: After running a meta-optimization pass that staged three candidate patches, invoke this Skill to jury-review and land only the patches you explicitly approve. ## Quick Start After reviewing the staged patches from a meta-optimize run, ask the agent to run meta-apply on the patch numbers you approve, such as patches 1 and 3.
